Slur in GC (literal reading→GE1)

Slur in GC, contextual interpretation

Slurs in FE

Slur in GE2 (→GE3), possible interpretation of GC

In the main text we give the most natural, according to us, interpretation of the notation of GC, including Gutmann's inclination to draw (too) broad slurs – cf. the Etude in A minor, No. 11, bar 9. The slurs of FE do not raise major concerns, in turn, the broken slur in EE seems to be a result of a misunderstanding – a context interpretation of the slurring of the base text to this edition could have led to the version of GE2 (→GE3). See also the note to bar 25.

b. 27

composition: Op. 25 No 10, Etude in B minor

F1-F in GC (→GE) & FE

F1-F in EE

..

The version of EE is vitiated by an uncertainty concerning its authenticity – it can be a mistake or revision, which cannot be stated without the manuscript base text to this edition or other additional pieces of source information. Therefore, in the main text we give the compatible version of the remaining sources. As far as the music is concerned, the version of EE seems to be less convenient, as it omits F in the progression of bass, without any specific reason, which is the base of the initial and final chord of the dominant in the B minor/B major key: (F)-E-D-E-F(!)-A.

In the main text we give  written by Chopin in GC in FE is most probably the original version – cf. bar 23, as well as bars 15-21.

b. 28

composition: Op. 25 No 10, Etude in B minor

..

In GC, FE and EE the only accidental before the last chord in the R.H. is the cautionary  before e1. According to us, the sign is not superfluous here, contrary to the  returning f1, which was added only in GE.

Crotchet rest in GC (→GE), FE & EE

Minim rest suggested by the editors

..

It does not seem that the fact of shortening this bar present in the sources – it includes only three crotchets – had any practical or expressive meaning, as it is compensated by the fermata over the final rest. Due to this fact, in the main text we suggest a minim for this rest, compatible with the time signature. Perhaps at an earlier stage of composing the Etude Chopin introduced here certain changes and did not check the rhythmic notation diligently.
The rhythmic values incompatible with the declared time signature appear in one of the autographs of the Nocturne in B major, Op. 62 No. 1, bar 67 – the bar with the 4/4 time signature is filled with a semibreve and minim.
